The autopsy results of two people who were killed Thursday in Evanston show that the victims died as a result of stabbing, police say.

Autopsies were performed Friday on Chona Manzano, 35, and her five-year-old son Gabrial after they were found in their northwest Calgary home Thursday. Police say a knife was recovered at the crime scene.

Guevera Wilson Clorina, 26, has since been charged with two counts of second-degree murder. Police believe he is related to the victims but is not an immediate family member.

According to police, a family member found the two bodies and then ran to a neighbour's house to call for help.

Police found the body of Chona Manzano on the main floor of the home.

Her son Gabrial was found on the second floor.

They were pronounced dead on the scene by EMS.

"We have a lot of folks that we're talking to, to try and figure out what's happened leading up to this event," said Kevin Brookwell, spokesman for the Calgary Police Service.

After police released details of a vehicle believed to be linked with the residence and it was located by RCMP hours later near Olds, which is 95 kilometres north of Calgary.

Police say the car was found in a ditch with Clorina inside.

He does not live at the same house as the victims.

Staff Sgt. Doug Andrus said two other children and the father, who he described as overwhelmed with grief, were not at home at the time.

"He's grateful for our investigation and that we've brought it to a conclusion so quickly, but it still doesn't replace the loss of a partner and a child," said Andrus.

Peer-support advisors have been called in to help the responders who were first on the scene and discovered the bodies.
